The earlier graphics are transfers, the revised graphics - at least, on TSD examples - are peel-and-stick. The only thing I am sure about is that I've never seen a post-'83 frame (Paolo Guerciotti's signature on seat stay caps) with the earlier decal set. Spoon-stay cap examples are as easy to find with the earlier set as the later, though the TSD 1978 showbike does positively indicate that the spoon caps and the earlier decal set were in use that year.

However, I've had an example with flat stay caps (marked "GUERCIOTTI") which was obviously produced sometime after 1978 due to Portacatena-ready 1010B dropouts. One might assume this variant came in between the spoon-cap variant and the Paolo G. caps, but they're unusual enough that I've only seen one other example; furthermore, quite a few spoon-stay cap examples have been claimed to be examples dating from as late as 1982 and 1983. Many of these also have the later decal set.

Doesn't make sense, does it? What is more, the flat-cap versions are virtually dead-on identical to a Benotto 3000, with exception to the cap pantographing and occasional variants in the headlugs (Benotto seemed to fluctuate in what headlugs they used on the 3000). I know Guerciotti supposedly never built a bike themselves, but neither the spoon-stay cap Gooch's nor the post-'83s have the slightest resemblance to any Benotto.

White wrapped around the downtube was used specifically on the AlAn-built aluminum frames, never on steel:
